STAMFORD, CT - In response to the state’s Mosquito Management Program’s announcement of mosquitoes in Stamford testing positive for West Nile virus, the City of Stamford’s Department of Health is enacting measures to control the local mosquito population and advises residents to address conditions that may attract mosquitos.

To control the City’s mosquito population, the Department of Health sprays insecticides in catch basins that specifically target insects in their larval-stage (also known as “larviciding”). This began in June earlier this year, and continued through July. The City will continue larviciding catch basins to prevent the development of adult mosquitos with the West Nile virus infection. Larviciding will continue on Monday, August 19, and repeat regularly through September.

In addition to these safety measures, homeowners and businesses should address conditions that may attract mosquitos such as standing water, discarded cans or bottles, and overgrown grass, bushes or shrubbery. Residents are encouraged to report instances of these conditions to Stamford’s Department of Health. Residents are advised to avoid outdoor activities at dawn or dusk and ensure all window and door screens are intact. If a resident must be outside, they are advised to use approved mosquito repellent and wear long sleeves and pants.

Mosquitoes with the West Nile Virus were reported in Stamford in 2018 and 2017. No human infections of the virus have been reported in Stamford this year. However, medical providers should consider the West Nile viral disease throughout peak mosquito season (July 1 to October 31) if a patient presents with unexplained encephalitis, viral meningitis, or acute flaccid paralysis. Patients may also present with symptoms compatible with West Nile, including: fever, maculopapular rash, headache, fatigue, weakness, joint and muscle pain as well as nausea, vomiting and diarrhea.

Medical providers should report all cases of West Nile virus to the City’s Department of Health.
